To all 'whom it may coiwemfj v Be it lnown that I, LEONARn DISoUnrnn,

afcitizen of the United States, residing at. Toledo, in the county of Lucas and State of Ohio, have invented new and useful Imrovements in Glass Feeders, of which the ollowing is a specification.

My invention relates to apparatus for feedlng charges of molten glass and particularly to a glass feeder of the type in which I the glass is discharged through an outlet opening' in the bottom of a container, the discharge being regulated yand controlled by means of a periodically reciprocated reguH lating plug projecting into the glass above the outlet.

In feeders of this type, the outlet opening is usually disposed in 'the floor of a furnace boot or extension, adjacent the forward end of the boot, and the regulating plug is reciprocat-ed in the main body of glass in\the boot and in line with the outlet o'peping An object of the .present invention is to provide means for segrcgating or separating from the main body of glass inthe container,

. a reduced quantity of glass commensurate away. s

with the volume of the charge to be delivered through the o'utlet, so that 'the effect of the regulating plug on the issuing/glass is more pronounced in both directions of its movement. This gives a bettery control ofl both the shape and size of the issuing gobof glass than 1s obtained with the.' usual an;

ranvement above mentioned.

lA furthe1"` object of the invention is to' provide suitable means for positively controlling and .directing the glass in its pasl sage from the main furnace to a position in register with the outlet opening in the floor of the boot. f/

A further object is the provision of a practical co struction for carrying out the ideas herein embodied.

Further ol jects will appear hereinafter.

In the accompanying dia' ings:

Figure l is a sectional sie elevation of apparatus jonstructed in -a ,toi-dance with my inventi n.

gure 4 is an elevation showing the driv ing gears 'for said glass-carrying niember.

Figure 5 is a sectional elevation of a modiicatlon.

Figure 6 is same.

Figure 7 is front sectional elevation of said modification.

A furnace boot or extension 10 (Fig. 1) is continuously supplied with molten glass 11 from a furnace 12.A The glass issues periodically tlnoughA an outlet opening 13 in a part sectional lplan of the Mounted on a vertically disposed shaft 17' "{itll projecting downward into the glass, is afglass-conveying member 18 (FLg. 3) constructed of refractory material and having formed therein a series of pockets 19. The walls 2() of these pockets are tapered .ro as to form with the well 16 and the front wall 21.

/ of the hoot, a funnel. shaped discharge chamber, when one of saidA pockets is in register with Said well.

The shaft l? is mounted for rotation in. a bearing bracket 22 supported by vertical --standards23 projecting from theboot casing 24C. Attached to the upper end of the shaft 17 is an intermittent bevel gear 25 running in mesh with an intermittent gear 26 mounted on a shaft 27, said shaftinounted in a bearing 28 on the bracket 22. [attached to the opposite end of the sha-ft 2'? is a sprocket 31, connected. by a drivechain 32 to a driving sprocket 33 on a drive shaft 34. Also mounted on the shaft 3st isa plungeroperating cam 35 which operates through a lever 36 fulcrumed at 37 to reciprocate the clay plunger 1li vertically. v

A. bearing bracket 40 (Fig. 2) supported hy standards, 4l of the boot casting 24, provides a bearing 42 for the stem of the clay plunger. The stem i3 is mounted. in a block i4 pivoted at 45 to a yoke 46, said yolre having a screw projection 47 extending' up- Mtl nevi.

Ward to a pivot block 48. The pivotI block 4.8 is pivot-ally connected at 49 to the lever 36. The elements above enumerated and de scribed form a link connection between the lever 36 and the plunger le which allows said plunger to be 'reciijirocated without any binding in the bearing "he screw 4:7 allows for vertical adiustmeiit of the lil plunger.

Referring to Figures. l and at, it will lic noted that tor each complete rotation fit the cam 35, the bevel gear 26 will also iiiaficc iii i complete rotation, and thereby rotate the gear 25 through, 90. Thus, the pluri il will make one complete reciprocatioii cach time a pocket i9 is brought into regista# with the. well 16.

Projecting outward from the Wall i@ i the boot is a guard (Fig. 3) ha arc-shaped .front Wall which, with l circular front Vall of the boot. fc. stantially circular chamber 51 iii wi carrier 18 is rotated. The purpose oi guard is to prevent the pockets l@ o L carrier after they are discharged at, the ontlet 13 from filling with glass, until they have passed beyond the lguard, thereby dirooting and controlling the main (zii-fi... or path of the glass and bringing; it

lo, line with the movement orf the pockets toward the outlet 13.

In operation, the regulator 'i4 is periodica-ily reciprocated vertically. "ii/hen the regulator has just reached its uppermost position, the carrier 1S is rotated so as to bring a pocketll into alignment with. the outlet 13, thereby 'loriniiripwith the well lo a funnel shaped chamber into which the regulator is projected. The down stroke of the regulator displaccs a quantity oi' glass, the amount depending; upon the length ot stroke and size or plunger. Owing to the fact that the discharge chamber is funnel shaped and so arranged as to shut oil" or isolate a quantity ot glass from the main body of glass, the expelling and retarding elicotof the regulator upon the glass is considerablv enhanced.

Figures 5, 6 and 7 show ay modification wherein the carrier is operated continuously. The driving' ii'icclianisiii tor this is the saine up to the shaft 2.7 Where the intermitlent gearing is replaced b v gears 51 and 52 on the liafts '2T and '1i' respectively. The carrier 53 on the shaft 1T is formed with pockets 54 therein, arranged to carry the glass to the outlet lil iii the boot floor. lt will be found that as the cari-ier rotates Iii-ingingr a new pocket into dischargingr position, when the projecting part of the carrier passes over the outlet i3, the yglass therein will be retarded, diie to the pull of the carrier upon the `glass. Fui-their, it ma)Y `be noted iliai as thc regulator l-l completes .its illoivii stroke. thciiioveniciit of the carrier vill assist in expelling glass and then abruptly,v cnt. cti' the spirit a uilflia; l. claim is:` l..
